摘要： A stabilized transmitter includes a gain converter that varies its gain according to an electrical signal; a power amplifier that amplifies a high-frequency signal passed through the gain converter; and a compensator having a temperature sensor which detects the temperature of the power amplifier for producing from a detection result of the temperature sensor the electrical signal applied to the gain converter so as to thereby to compensate for variations of the gain of the power amplifier caused by temperature variations. The compensator is adjusted in advance so that the gain of the power amplifier at a reference temperature becomes a predetermined value.

摘要： A display apparatus for displaying any data on split blocks on a display screen of a CRT. The apparatus comprises a circuit for producing a horizontal address and a vertical address of a display position on the display screen; a block address generator comparing the horizontal and vertical addresses of the display position with predetermined horizontal split addresses and vertical split addresses for generating a block address which shows one of the split blocks on the display screen according to the comparison result; a code converter for converting the block address to a predetermined code; a memory start address generator for generating a memory start address according to the code outputted from the code converter; a memory address generator for generating a memory address from the memory start address and the horizontal and vertical addresses of the display position; a display memory storing display data and output the display data according to the memory address; and a display monitor for displaying the display data outputted from the display memory on the CRT.
